2 Claims. (Cl. 144--297) This invention relates to tools used primarily by carpenters, and in particular a bracket having a U-shaped base adapted to be positioned over a joist and a finger adjustably mounted on the base and positioned to hold a board in nailing position against the joist.

The purpose of this invention is to facilitate nailing sheathing to wall studding and ceiling joists, particularly with one man working alone wherein one end of a board is held by the bracket as the opposite end is nailed in place.

Nailing sheathing to wall studding and ceiling joists requires considerable time because it is difiicult to hold the sheathing in position as the first nails are started into a board, and in numerous instances this is even difficult with one carpenter holding one end as another nails the opposite end. With this thought in mind, this invention contemplates a bracket adapted to be readily clamped to studding, joists, and the like, with which one end of a board is positively held in position as the other end is nailed.

The object of this invention is, therefore, to provide a bracket that may readily be positioned on a joist or stud wherein a U-shaped holder is provided so that a board is held on both sides or definitely supported on a horizontally disposed arm whereby an end opposite to the end being held by the bracket may be accurately positioned and positively nailed in place.

Another object of the invention is to provide a board retaining bracket that is adapted to be used on conventional studding and joists and that is readily adjustable to joists and studding of ditferent sizes.

A further object of the invention is to provide a board retaining bracket particularly adapted for retaining sheathing in position as it is nailed to studding and joists in which the bracket is of a simple and economical construction.

With these and other objects and advantages in view, the invention embodies a bracket having a U-shape base with an elongated finger extended from one side of the base and an Lshape support having an elongated slot in a base thereof with a finger extended from one end of the base and in which the support is secured to the U-shape base with studs having thumb nuts thereon.

Other features and advantages of the invention will appear from the following description taken in connection with the drawing, wherein:

Figure 1 is a perspective view illustrating the use of the board retaining bracket showing the bracket positioned on a ceiling joist and also showing a board adapted to provide sheathing for a ceiling resting on a finger of the bracket.

Figure 2 is a cross section through the bracket taken on line 22 of Figure 1 with the parts shown on an enlarged scale.

Figure 3 is a perspective view illustrating the use of the bracket for holding sheathing against wall studding.

Figure 4 is a detail show-ing an exploded view illustrating one of the studs and thumb nuts for clamping the support in adjusted positions on the U-shape base.

Referring now to the drawing wherein like reference characters denote corresponding parts, the improved board holding bracket of this invention includes a U-shape base 10 having arms 11 and 12 extended downwardly from the ends thereof and having a finger 13 extended from one side, and an L-shape support having a base 14 with an elongated slot 15 therein and having a finger 16 extended from one end.

The support is adjustably mounted on the arm 11 of the U-shape base 10 with threaded studs 17 having square shanks 18 adapted to be positioned in correspondingly shaped openings 19 in the arm 11 and having heads 20 positioned at the ends of the shanks, and the studs are held in position with the threaded ends 17 extended through the slot 15 of the base 14 with thumb or wing nuts 21 and lock washers 22. The studs are positioned with the square shanks in the portions 19 of the openings and the heads 20, which are positioned in counter-bores or annular recesses 23 are adapted to extend beyond the surface of the arm 11, as shown in Figure 2, whereby the heads 20 of the studs 17 bear against the surface of a joist or stud, as indicated by the numeral 24.

The bracket may also be retained in adjusted positions with a thumb screw 25 which extends through the slot 15 and which is threaded in an opening 26 in the arm 11 of the U-shape portion or base of the bracket.

With the parts designed and assembled as shown and 7 described, a carpenter places the Ushaped base 10 against the far side of a stud, as illustrated in Figure 3, with the finger 16 extended downwardly and with a board, such as the board 27, positioned against studding 28, the opposite end of the board may be nailed to the studding without danger of the end held by the bracket, as illustrated in Figure 3, slipping from the board below.

In the design shown in Figure l the U-shape base of the clamp is positioned over a ceiling joist, such as the joist 29, and with the parts in this position the finger 13 rests upon the upper surface of the joist with the finger 16 extended below the joist, a distance substantially equal to the thickness of a board, such as the board 30. With the sheathing board held in this manner the board may be nailed at the opposite end and throughout the intermediate porition thereof to the joist with the bracket retaining the board in position.

It will be understood that although the bracket is illus trated as being particularly adapted for holding sheathing against wall studding and ceiling joists it is also adapted for use for various other purposes.

It will be understood that modifications, within the scope of the appended claims, may be made in the design and arrangement of the parts without departing from the spirit of the invention.

What is claimed is:

1. A board holding bracket comprising a U-shaped base having arms extended from a connecting element, said element having an elongated finger extended from one side edge thereof in a direction at rightangles to that of said arms, an L-shape support having a base with an elongated slot therein, stud bolts with thumb nuts thereon mounted in one of the arms of the base and extended through the slot in the base of the support and a thumb screw threaded through the arm of the base in which the studs are positioned and extended through the slot in the base of the L-shape support for retaining the bracket in position on a joist.

2. In a board retaining bracket, the combination which comprises a U-shaped base having parallel arms extended from ends of the connecting member and having an elongated finger extended from one side edge of the connecting member in a direction at right angles to that of said arms, and an L-shape support having a base with an elongated slot therein, threaded studs mounted in one 1 3 4 arm of the U-shape base and extended through the slot 937,480 Smith et a1.
